在 Angular 中更新表行数据

Update table row data in Angular

本文关键字：数据 更新 Angular      更新时间：2023-09-26

您好，我正在学习角度，我需要功能方面的帮助，我有一个动态表和一个表单，当我单击动态表的任何行时，数据应该填充在表单的输入框中，当我编辑数据并将其保存在输入框中时，这些输入框应反映相同的更改。

 $scope.Save= function($index){
    		
    		 var user1= angular.copy($scope.displayData[$index]);
    		 fc.saveData.push(user1);
    		 console.log(fc.saveData.name);
    }}
 
<head>
    <script src="https://code.angularjs.org/1.4.9/angular.js"></script>
</head>
<table class="table2">
    <tr>
        <th>Player</th>
        <th>Age</th>
        <th>Ranking</th>
    </tr>
    <tr ng-repeat=" usr in saveData" ng-click="fnClick(usr)">
        <td>{{$index}}</td>
        <td>{{::usr.player}}</td>
        <td>{{::usr.age}}</td>
        <td ng-bind="::usr.ranking"></td>
    </tr>
</table>` and my input boxes code is here `
<div>
    <button class="btn" ng-click="Savedata()">Saveintable</button>
    <label for="field1">
    	<span>Name</span><input type="text" name="" required="true" ng-model="displayData.name"/>
    	</label>
    <label for="field2">
    	<span>Age</span><input type="text"  required="true" ng-model="displayData.age"/>
    	</label>
    <label>
    	<span>Ranking</span><input type="text" ame="" required="true" ng-model="displayData.ranking"/>
    	</label>
    </label>
</div>

var app=angular.module("myApp",[]);
app.controller("startCtrl",function($scope){
     $scope.saveData=[{
     player:"John",
     age:"24",
     ranking:'1' 
     },
     {
     player:"John1",
     age:"25",
     ranking:'2'
     },
     {
     player:"John3",
     age:"26",
     ranking:'3'
     }];

     $scope.fnClick=function(usr,index)
{ 
      $scope.formData=angular.copy($scope.saveData[index]);   //usr object will be assigned to $scope.formData...
     $scope.formData.index=index;
     console.log($scope.formData);
}
 $scope.SaveDataFun= function(formData){
           console.log('save data');
            var index$=formData.index;
            console.log(index$);
             // now I assume that displayData is a list of objects.
           angular.forEach($scope.saveData,function(data,index){
                   console.log(index +' '+ index$);
                   if(index==index$) // this will match your ediated row index$ to displayData objects row index.
                   { console.log('if')
                         console.log(data);
                         $scope.saveData.splice(index,1);
                         $scope.saveData.splice(index,0,formData);
                                             console.log(formData);
                         $scope.formData={};
                                    }
                    });
       }
});
